CREAM Flights 
Here are progresses done from last Saturday to today at CSBF related with the CREAM-V integration. (There have been network problems in the CSBF from Monday so we can not check or send e-mails during work hours at the CSBF until we come back to Hotel late night.)
- Installations of heat pipes for the SCD and Chercam including heat dissipation panels were completed by Fritz and Scott.
- Four side foam walls were prepared and 3 of them have been installed today by Fritz.
- With the new IDE cables brought from UMD, all of IDE cables in both SFC1 and 2 were replaced by Hoseok.
- The instrument CPT with SFC1 via Ethernet connection has completed this afternoon except the Master Trigger board test which requires preparation of another MT board. It will be done as soon as time found. The data and plots will be copied to the cdps3 manually as soon as the network recovered. They look the same as what we saw at UMD.
- During the CPT, we found that the trigger cable to the CAL sparsification board is too tall to fit between the board and the upper box and causing noisy data as reported by SangEun before. Another cable without a plastic sleeve will be used for the board.
- The SFC2 is being prepared for the LPT tonight. The remaining LPT will be done tomorrow.
- The power cable from the SIP was prepared by refurbishing the flight cable for the CREAM-IV by Chris and Joseph. It is tested as good to fly and have additional pins(1&2) connected for the existing TCD power (4&5) for higher current.
- The thermistor cable for the CREAM-IV flight also retested and found to be good to fly.
- The lengths of power/thermistors/heaters cables were measured and given to Chris for productions. But only the one for the heaters will be used for the production since the others are available already as explained in the above.
- SIP integration planned tomorrow. First the SIP without the power will be connected and tested to make sure that it is working with the instrument. After that, the power will be connected to the instrument and the integrated CREAM-V will be tested.
- Remaining LPT with the SFC2 will continue.
- Remaining CPT of the MT part will be continue.
- HSK board check for the old problem with the Chercam channels and new issues with TCD/CD HV channels. There was a report by Tyler on a drifting of HSK values for two TCD HV channels even though those two channels did not drift when were connected to another good HSK channels for a few hours.
- Live time ratio measurement with the SIP configuration. The ratio has improved after a debugging work. But it was not as the same or stable as the CDM configuraiton of about 90% with the 20Hz trigger rate. This is the critical issue whether we can fly in the SIP configuration or not assuming that the other SIP integrations working fine.
It is not clear whether we can have a good network connection tomorrow yet. Please try the telephone, 903-731-8569 (CSBF high bay), if you want to contact any of us.
